The linehaul pays for driving. Accessorials pay for everything else a load costs you: waiting at the dock, sitting overnight, a cancelled load, helping unload, extra stops. They are easy to earn and easy to lose. This accessorial charges calculator turns the hours and counts into invoice lines, using the rates you agreed, and lists the proof each line needs.
How it is calculated
| Line | Formula |
|---|---|
| Detention | (hours at the dock − free time) × hourly rate, never below zero |
| Layover | days × daily rate |
| TONU | flat fee, if the load was cancelled after dispatch |
| Driver assist | hours × hourly rate |
| Extra stops | stops beyond the first pickup and delivery × per-stop rate |
| Lumper | the receipt amount, reimbursed |
All rates are yours to enter. There is no standard detention or TONU rate across the industry; they come from your rate con, your carrier packet or what you negotiate. The defaults on the tool are examples only.
A worked example
- Detention: 4 h at dock, 2 h free, $50/h
- $100
- One extra stop at $75
- $75
- Lumper receipt, reimbursed
- $185
$175 of that is earnings for time and work beyond the linehaul. The $185 lumper just gets you back to even. If any line lacks its proof, expect a short payment.
What makes an accessorial collectable
- Agreed before the load. Detention and layover rates belong on the rate con. Verbal promises are the first to be disputed.
- Proof at the time. In and out times written on the bill of lading and signed, lumper receipts, cancellation emails.
- Approval when it starts. Message the broker when free time runs out, not after delivery.
- Invoiced with the load. Extras sent weeks later are the easiest to deny.
Dock waits get their own detail in the detention pay calculator, and the dispatch fee on a load is worked out in the dispatcher fee calculator.
Power only and port moves
Power only and drayage loads add their own extras: waiting for a trailer to be found in a yard, chassis splits, pre-pulls and storage at the port. Terminal access needs its own credentials, covered in port truck pass. How those extras change what a power only load pays per mile is in power only rates per mile, and how we run those loads in power only dispatch.
Results are line items from the numbers you enter, not a guarantee any broker will pay them.
